(there's also podgourmet and pocket vegan (which appears to be the same thing, or at least from the same developer) and that's for any ipod, but they cost 7.50. and it's not an application, but a download.)
there's also icookbook and chef, but those don't stand out to me. if any of you know how to build applications, let me know. maybe we can make one based on the recipes that are posted here. it'd be nice to have an application that was all vegan recipes.
so-far i'm using the files application and caravan and accessing word documents that i put together and save onto the ipod. and that works really well, but it'll be nice if it was internet based and updated whenever there's a new recipe that's posted. but that'll be a lot of work.
